Title: Improvements in or relating to liquid pressure remote control systems
IPC: G05D13/00
Filed: 1937-03-20
Abstract: 486,238. Hydraulic transmission of power. AUTOMOTIVE PRODUCTS CO., Ltd., and CLENCH, E. C. S. March 20, 1937, No. 8278. [Class 69 (ii)] A liquid pressure remote control system comprising a transmitter cylinder and piston having actuating means, a slave cylinder and piston, a single pipe connecting said cylinders, and a return spring adapted to move the slave piston forward as the transmitter piston is retracted, is characterized by the provision of locking means which are automatically rendered operative by the action of letting go the actuating means. The transmitter piston 14 has a connecting rod 16 secured by pin 18 to member 19 pivoted on a spindle 20; the member 19 carries a part 35 forming with the inner face 34 of the transmitter casing convergent spaces receiving rollers 36, 37 carried by springs 38 secured to the member 19, these rollers serving to lock the member 19, and thus the transmitter piston, in set position. An actuating lever 40 has a boss 42 mounted on the centre part 43 of the member 19, and a lug 44 in which is a hole 47 embracing the pin 18 with clearance ; when the lever 40 is moved in either direction, a part 46 carried thereby releases the appropriate roller 36, as shown in Fig. 5, and the slack having been taken up, the member 19, and together with it the piston 14, are then moved. On releasing the lever 40, the spring 38 forces the roller 36 back into locking position. A spring arrangement 30, 31 urges the transmitter piston 14 to its forward position shown. The slave piston 62 is then in its retracted position, the spring arrangement 69, 70 being fully compressed, and the pipe line 10 communicating through holes 76 in the piston with an annular chamber 75 ; should the temperature rise when the parts are in this position, excess liquid will pass through non- return valve 81 to an accumulator comprising a spring loaded piston 78. When the transmitter piston is unlocked and retracted, liquid returns to the pipe line through non-return valve 84 and passage 85 which is in constant communication with the pipe line 10. The springs 69, 70 urge the slave piston 62 forwardly as the transmitter piston 14 is retracted, the springs 30, 31 opposing the springs 69, 70. The springs employed in the transmitter and receiver units may have variable rates in order to compensate substantially for the change in the moment which they exert about the pivots of the respective lever arms. When the transmitter piston 14 is fully retracted, ports 52 therein place the pipe line 10 in communication with the reservoir 12 to permit " breathing." A bleed plug 55 is provided.

[Also in Division C3] A method of bonding a sulphur vulcanizable synthetic rubber composition comprising an interpolymer of ethylene, an alpha-mono-olefin and one or more unsaturated compounds conferring unsaturation on the interpolymer to a surface of steel, brass or zinc, comprises mixing the interpolymer with sulphur and a cobalt salt in an amount such that the synthetic rubber composition has a metallic cobalt content of from 0.09% to 1.5% by weight based on the weight of the interpolymer and vulcanising the composition while it is in contact with the surface. The cobalt salt may be that of an organic or an inorganic acid. Specified are, cobalt naphthenate, linoleate, stearate, oleate, acetate or resonate and cobalt dichloride. The sulphur may be present in amount from 0.5 to 15 parts by weight per 100 parts by weight of the interpolymer. The composition may also include an accelerator, carbon black, an extender oil, a pigment, or a metal oxide or hydroxide. After application to the metal surface the composition may be vulcanized in the presence of steam under pressure at a temperature of from 150‹C. to 180‹C. Numerous suitable synthetic rubber interpolymers are specified. They may consist wholly of an interpolymer of ethylene, an alpha-mono-olefin of one or more unsaturated compounds which confer unsaturation on the interpolymer or, mixtures of such interpolymers with one or more other sulphur-vulcanizable polymers. Suitable unsaturated compounds are straight-chain and cyclic polyolefins, such as diolefines, such as butadiene, isoprene, piperylene, cyclopentadiene, a hexadiene, a heptadiene, a cyclo-octadiene, a dicyclopentadiene, a dycycloheptadiene, 1,4-endomethylene, hydrind-2,6-diene, a tricyclopentadiene and a tetracyclopentadiene.

Title: Improvements in electronic control and coupling circuits
IPC: G11B5/02
Filed: 1956-03-20
Abstract: 821,632. Electric digital data storage apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. March 20, 1956 [March 23, 1955], No. 8598/56. Class 106 (1). [Also in Group XL (c)] The Figure shows the connections of the " read " amplifier and " write " amplifier of a magnetic recording system to a common " read write " head in which " bits " of information to be recorded are characterized by a reversal of polarity of the " write " signal input terminals 10, 11. When a signal is to be recorded a " write " instruction control signal lowers the potential of terminal 12 so that tube V8B is cut off and the " write " amplifier tubes V9A, V9B are in their normal position of conductivity. During the process of writing, if, for example, terminal 10 is up and terminal 11 is down so tube V9B is on and tube V9A is off, current flows through coil L1B and diode D1 and tube V9B. Accordingly when the polarity of terminals 10 and 11 is reversed current flows through diode D2 and coil L1B and tube V9A so that the magnetic surface is polarized in the opposite direction. When information is to be read off the " write " instruction control signal at terminal 12 is up so that tubes V9A and V9B are cut-off and the information is fed via " read " amplifier tubes V1A, V1B to produce an output signal at terminals 15, 16. Spurious noise signals which may be coupled through the grid/plate capacitance of either of the " write " output tubes V9A and V9B will be applied to the cathodes of diode D1, D2 but the diodes are non-conductive whenever the " write " output tubes are cut off and the noise signals will be dissipated across the back resistance of the diode and will not substantially effect the " read write " head. The diodes therefore act as a switch between the " write " amplifier and the " read write " head.
